KeyMapper VS TapTap

Key Mapper app of your choosing. (this is so you can access the home menu of launcher you decide to install since the home button will just take you back to the adth app they use) I will use this one: https://github.com/keymapperorg/KeyMapper

Key Mapper itself is FLOSS (Free/Libre open-source software), the source code is here. Another possibility is Volta, but Key Mapper is better.

I really do need to trigger these bindings programmatically: I'm using bash's keybinding functionality to supplement an app called Key Mapper which is no longer being actively developed. I'm using Key Mapper to execute shell scripts in Termux. These shell scripts contain variations of the printf command from above which trigger my bash keybindings.

Using Key Mapper (https://github.com/keymapperorg/KeyMapper) (https://docs.keymapper.club/user-guide/adb-permissions/), I have assigned camera button + # button to lunch the keikai launcher, and I had to reassigned the camera button to open the camera.

FYI you can remap any button on your remote to open Plex (or other app, function) with KeyMapper https://github.com/keymapperorg/KeyMapper

Do you mean with a BT keyboard attached to the tablet? One approach is to use keymapper:

market: https://play.google.com/store/apps/details?id=io.github.sds1...

github: https://github.com/keymapperorg/KeyMapper

fdroid: https://f-droid.org/packages/io.github.sds100.keymapper/

It's a very versatile tool, can be handy even if you don't have a keyboard.

using the program KeyMapper how can i make holding a button toggle a light bulb in home assistant?

I don't know if it's the same with the onn, but with the google device you can use the Key Mapper app.

You'll have to see where the service capabilities are listed. This'll be xml folder here -> https://github.com/keymapperorg/KeyMapper/blob/master/app/src/main/res/xml/config_accessibility_service.xml

I never got much out of Easer, but I did come across Key Mapper, which lets you assign actions to button presses. I set up a mapping so that a double-click on volume down will activate the flashlight. Not quite as cool, but it's a pretty decent alternative.

Tap, Tap (version 1610): double tap on back of device

This app has double tap with sensitivity adjustment, works perfectly for me with no noticeable battery drain. https://github.com/KieronQuinn/TapTap

Just a quick shout-out of an app I discovered, it's a backport of quick tap for older android versions, but also has sensitivity adjustments and works great for me. Always triggers when I double tap (unlike the originl) and I've never had it accidentally trigger. https://github.com/KieronQuinn/TapTap

That said, some apps do use Material Design 3: Sync, Simple File Manager, Auxio Tap, Tap

Github

Tap Tap provides customizable tap routines

Tap, Tap (version 1600): double tap on back of device
